The bottom bracket where 3 frame arms meet is supplied with ball or roller bearings which are able to reduce friction very substantially.

The difference is the size of the hole in the center of the bearing. A 19mm bottom bracket will fit a 19mm crank spindle (profile cranks have a 19mm spindle). A 22mm bottom bracket will have a hole in the center that is 22mm. a 22mm spindle (eclat tibia cranks have a 22mm spindle) will fit in the 22mm bottom bracket. The size of the bottom bracket needed depends on the size of your crank's spindle size.

What is the difference between a Euro American Spanish and mid bottom bracket?

American bottom brackets can be recognized because they have the largest bearing cups you'll find, and the crank that fits into them is a one-piece design (it's also called an Ashtabula crank). This type of BB is usually found on entry-level bicycles. To take this BB apart, you need to first remove the left pedal (turn it clockwise to remove it). Then you can easily take the American BB apart with plumber's pliers. Euro bottom brackets are the smallest and usually the lightest style of bottom bracket. You use BB tools to remove the crankarms and remove the BB cups from the frame so that you can service the bearings.Mid bottom brackets are a press-fit design, which means you can press in and pull the bearings out with your hands. These BBs use medium-size bearings and are found typically on high-end bikes. Spanish bottom brackets were invented by a company called Fly bikes. They use the Mid bottom bracket design and reduce the size of the bearings, thus reducing weight a bit. They share the press-fit design for easy assembly/disassembly. Spanish BBs are favored by pro BMXers.

What size is your haro f1 09 bottom bracket?

A Haro F1 uses a "standard USA" bottom bracket with press-in cups (as opposed to a "Euro" bottom bracket, like what road and MTB bikes use). These bottom brackets don't come in sizes because there's only one size. Bottom bracket spindles do, however, vary based on the crankset you're using. If you're talking about the Haro Fusion cranks that come with that bike, you're talking about a 19MM, 8 spline spindle, which is actually pretty standard.
